In this study, we designed and synthesized a hydrazone compound <jats:bold>1<\/jats:bold>, ethyl (Z)\u20102\u2010(2\u2010([2,2\u2032:6\u2032,2\u2032\u2032\u2010terpyridin]\u20104\u2032\u2010yl)hydrazineylidene)\u20102\u2010(4\u2010(diphenylamino)phenyl)acetate, which possesses a push\u2010pull structure incorporating triphenylamine and terpyridine. The emission intensity of compound <jats:bold>1<\/jats:bold> can be repeatedly switched \u201coff\u201d and \u201con\u201d by irradiation with visible light and UV light, which induces the isomerization transition between the Z and E forms. In addition, compound <jats:bold>1<\/jats:bold> is capable of changing its emission wavelength from 540\u2005nm to 607\u2005nm through coordination with different zinc salts in toluene\/CH<jats:sub>2<\/jats:sub>Cl<jats:sub>2<\/jats:sub> mixture (v\u2009:\u2009v=1\u2009:\u20091). Importantly, we have successfully achieved dynamic manipulation of fluorescence color and intensity by altering the counterions of zinc complexes and switching the isomer from Z to E. Moreover, both compound <jats:bold>1<\/jats:bold> and its zinc complexes demonstrate remarkable photoswitchable properties with different fluorescence colors in the thin films. Finally, these films with various fluorescence colors were used for the production of luminescent tags.<\/jats:p>","DOI":"10.1002\/asia.202300708","type":"journal-article","created":{"date-parts":[[2023,9,15]],"date-time":"2023-09-15T10:29:23Z","timestamp":1694773763000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Dynamic Metal\u2010ligand Coordination for Fluorescence Color Regulation of Hydrazone\u2010based Bistable Photoswitches"],"prefix":"10.1002","volume":"18","author":[{"given":"Diankun","family":"Zhang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Organic Electronics and Information Displays &amp; Jiangsu Key Laboratory for Biosensors Institute of Advanced Materials (IAM) &amp; Institute of Flexible Electronics (Future Technology) Nanjing University of Posts and Telecommunications (NUPT)  Nanjing 210023 P.
